The first clamping member 2 and the second clamping member 3 are arranged on the base plate 1 at intervals along the first direction X, and are used to clamp the track therebetween. The first clamping member 2 includes a first side plate 21, an outer flange 22, an elastic pressure plate 23 and a bolt 24. One end of the first side plate 21 is connected to the base plate 1, and the end of the first side plate 21 close to the base plate 1 is provided with an outer flange 22, and the end of the first side plate 21 away from the base plate 1 is connected to the elastic pressure plate 23, a through hole 231 is provided on the elastic pressure plate 23, and a threaded hole 211 corresponding to the through hole 231 is provided on the first side plate 21, and the bolt 24 passes through the through hole 231 and is screwed into the threaded hole 211. By tightening the bolt 24, the elastic pressure plate 23 can press the outer flange 22 onto the track, thereby clamping the track between the outer flange 22 and the second clamping member 3.

[0033] The connection structure of this embodiment can be clamped and connected to the rail by tightening the bolts 24. It has a simple structure, is easy to operate, saves time and effort, is easy to assemble and disassemble, and can effectively improve construction and maintenance efficiency.
